Compatibility problem with Symfony Serializer going from 5.2.4 to 5.2.5

[YetiCGN]

PHP version: 7.3.7
Elasticsearch version: 5.6.16
Bundle version: 5.2.5
Symfony version: 3.4.37

Going from 5.2.4 to 5.2.5 you raised the version range for ongr/elasticsearch-dsl from ~5.0 to ~5.0|~6.0. This causes problems with the Symfony Serializer in version 3.4, which does not yet have type hinting:

Compile Error: Declaration of ONGR\ElasticsearchDSL\Serializer\OrderedSerializer::normalize
($data, ?string $format = NULL, array $context = Array) must be compatible with
Symfony\Component\Serializer\Serializer::normalize($data, $format = NULL, array $context = Array)

The problem is easily fixed by declaring a conflict with ongr/elasticsearch-dsl: "~6.0" in the project composer.json or by pegging the version to something 5.x. But in my opinion, the bundle should not raise the version constraint on a point release. Unless you have a good reason for it?
